Definitions

  • the invention relates to a chain conveyor according to the preamble of claim 1.
  • the chain conveyors in question are generally used in storage compartments of rack storage facilities, where they serve as funding for the goods to be stored.
  • the conveying means is usually looped over two deflections to form a continuous conveying means, wherein a conveyor chain provided with rollers is provided as the actual conveying means.
  • circulating conveyor is designed as a chain, but only about half, while the other half is formed by a webbing.
  • pallets are used.
  • the goods are placed on the conveyor chain and, usually by a forklift, pushed into the shelf. If necessary, the goods are pulled out of this forklift also again.
  • a "pallet support rail for conveying pallets and containers” generic chain conveyor is known.
  • This is provided with a roller chain, the support rollers are connected in pairs on both sides by a pair of side plates, each second link of the chain is designed as a support strap on which the goods to be stored can be supported.
  • the side flaps project downwards so far that they can guide the upper run of the roller chain laterally along the running rail, the running rail being smaller in width than the distance between the two side flaps of a pair.
  • the running rail made of aluminum has a return channel, in which the lower run of the roller chain is received, guided and supported vertically.
  • the problem with the described chain conveyor is that the side plates of the roller chain must absorb both tensile and executive forces.
  • the side flaps can not be made continuously from a base material having good, self-lubricating properties such as PTFE, but they must be at least partially made of a high strength material, such as steel.
  • This design has the disadvantage that the coefficients of friction between roller chain and guide rail are relatively high. This is especially true for the lower, in the return anal recorded chain center, since in addition the weight of the roller chain must be taken from the side flaps. Due to the high, resulting between roller chain and mounting rail coefficients of friction, the length of such a configured chain conveyor is limited. In addition, it has been shown that the frictional resistance is additionally increased by the tensile load on the simultaneously formed as a guide means side flaps.
  • Another object of the invention is to provide a chain conveyor which is formed with means for laterally guiding the roller chain, which can be easily arranged and manufactured inexpensively, the guide means should come up with very low frictional resistance between roller chain and mounting rail.
  • Figures 1 to 3 a single tab for a roller chain in three different views.
  • FIG. 10 shows a cross section through a mounting rail and through the roller chain.
  • Fig. 11 is a plan view of a portion of a roller chain, which is provided with tabs ACCORDANCE Figures 1 to 3;
  • FIG. 12 shows the section of the roller chain according to FIG. 11 in a side view
  • Figs. 1 to 3 show a tab 1 for a roller chain in an elevation, a side elevation and a floor plan.
  • Replacement Blade (RULE 26) 1 is formed substantially U-shaped and has a base part 10 and two legs 11, 12. The lying between the two legs 11, 12 base member 10 forms the upper cover of the tab 1. Both legs 11, 12 of the tab 1 are provided with holes 13, which is the recording of a respective shaft for connecting the tabs 1 and for storage and Ab - support of idlers.
  • the base part 10 of the tab 1 is provided with two along the one leg 11 arranged recesses 16 whose width b2 is greater than the wall thickness of a leg 11, 12. Through these recesses 16, the joining of a plurality of uniformly formed tabs 1 is favored to a chain by a leg 11, 12 of a preceding or succeeding, rotated by 180 ° about the vertical axis, lug 1 engages in such a recess 16.
  • the base part 10 is also provided with a transverse to the longitudinal axis slot 15.
  • This slot 15 serves to receive a carrier made of an elastic material, as will be explained in more detail below with reference to FIGS. 7 to 9.
  • the basic shape of such a tab 1 is preferably made by punching, while the U-shaped configuration is produced by subsequent bending of the punched-out part.
  • the two end portions 17, 18 of the base part 10 of a tab 1 are preferably formed obliquely.
  • the two end portions of the base part may also be provided with a gradation, as indicated by broken lines L drawn.
  • the one leg 12 is provided with two protruding beyond the top of the base member 10 elevations 14, wherein for manufacturing reasons each of the shorter portion 17 a, 18 a
  • FIGS. 4 to 6 show a guide element 2 for the roller chain in three different views.
  • This guide element 2 consists essentially of a guide plate 21 and a clamping part 24. On the inside of the guide plate 21, a strip 23 is formed.
  • the lower portion 26 of the guide plate 21 serves the lateral guidance of the roller chain while the guide plate 21 has on the upper side a bearing surface 25 which is formed at a circumferential chain for supporting the lower chain center.
  • the operation of this guide plate 21 will be explained in more detail with reference to FIG. 10.
  • the driver 19 in an elevation, a side elevation and a floor plan.
  • the preferably made of rubber driver 19 serves as a support for the goods to be supported on the tabs.
  • the driver 19 has a holding part 15 which is formed corresponding to this slot.
  • the holding part 15 is guided through the slot and the driver is then rotated by 90 °.
  • the driver 19 preferably protrudes slightly above the elevations of the tab so that light goods do not rest on the elevations but on the driver. Due to the elastic design of the driver 19, however, it is ensured that heavy goods squeeze the driver and thereby get up on the surveys, whereby a secure, non-positive connection between the tab and aparlagernden goods pallet is ensured.
  • the support rail 5 has on the top of an upwardly stepped tread 6, which is bounded laterally by two guide surfaces. On the bottom is the support rail 5 with a downwardly open cavity H.
  • ISAEP provided, in which two auxiliary rails 7 are arranged, on which rest the guide plates 21 of the guide elements 2 with their support surfaces 25 and the lower chain 8b support vertically.
  • the roller chain 8 is formed by a plurality gemass Figs. 1 to 3 formed tabs 1 and support rollers 3, wherein in each case two tabs are connected by means of a shaft 28 hinged together.
  • the shafts 28 also serve to support the carrying rollers 3.
  • a guide element 2 is passed, which projects beyond the lug 1 on one side downwards.
  • the clamping part 24 of the guide element 2 engages behind the leg 12a, whereby both the shaft 28 and the guide element 2 are fixed in the position shown here.
  • a locking pin 29 are provided, which is anchored self-locking.
  • ISA / EP Fig. 11 shows a plan view of a portion of a roller chain, which is provided with uniform tabs 1 gemass Figs. 1 to 3 and guide elements 2 according to FIGS. 4 to 6. From this representation it can be seen that the tabs la, lb, lc, ld are arranged alternately rotated by 180 ° about their vertical axis, and that the one opposite to the other tab la, lb, lc, ld seen in the longitudinal direction of the roller chain 8, in each case the wall thickness of a leg of a tab la, lb, lc, ld is offset, so that in each case one leg 11, 12 of a tab engages in the recess 16 (FIG. 3) in the base part of the adjacent tab.
  • This design allows the tabs la, lb, lc, ld to also absorb and transmit lateral forces.
  • the average length L of the base part 10 at least approximately corresponds to the axial distance A between two adjacent support rollers 3.
  • the base part 10 is preferably about 0.5 to 3 mm shorter than the axial distance between two adjacent support rollers 3, so that in the extended state of the chain between the end faces of adjacent base parts 10b, 10c of adjacent tabs 1b, 1c, a gap b in of the order of magnitude of 0.5 to 3 mm.
  • This design has the effect that the mutual rotational movement of adjacent tabs beyond a predetermined angle is limited by abutting the end faces of adjacent base parts when the tabs rotate back against one another.
  • the end faces of adjacent base parts of adjacent tabs are formed correspondingly.
  • Such trained roller chain can thus transmit thrust, without the risk that the chain folds on individual sections.
  • FIG. 12 shows the section of the roller chain according to FIG. 11 in a side view. From this representation, the alternately arranged guide elements 2 can be seen, which extend beyond the tabs down.
  • Such a ausgestalteter chain conveyor is very simple and can be manufactured inexpensively, since both the tabs and the guide elements are uniform. By providing stops which limit the mutual, beyond a predetermined angle rotation of adjacent tabs in the manner previously described, the roller chain can also transmit shear forces.

Abstract

Transporteur à chaîne présentant une chaîne à rouleaux (6) et un rail porteur (5) pour l'appui vertical de la chaîne à rouleaux (6). La chaîne à rouleaux (6) comprend une pluralité de rouleaux supports (4) qui sont reliés entre eux au moyen d'éclisses (1). Les éclisses sont en forme générale de 'U' à deux branches (11, 12) et une base (10) s'étend entre celles-ci. La longueur moyenne (L) de la base (10) correspond au moins approximativement à la distance entre axes (A) de deux rouleaux supports adjacents (3). Les parties latérales des bases voisines d'éclisses adjacentes sont réalisées de manière correspondante et agissent comme butées, du fait qu'elles limitent la rotation relative d'éclisses adjacentes lorsque celle-ci dépasse un angle prédéterminé, de telle façon que la chaîne à rouleaux puisse transmettre des forces de poussée. Pour le guidage latéral de la chaîne à rouleaux, il est prévu des éléments de guidage distincts qui sont introduits au travers des axes reliant de façon articulée les éclisses entre elles.
